I never got an answer to this question...after about 5 hours of
searching everything under the sun, it occurred to me that the dialog
was getting resized when it was reactivated after the first time.
Evidently, the m_bFullScreen hack is NOT considered by the parent
class, at least not after it's loaded and displayed the first time.

The solution was to override the OnActivate and comment out the call
to the parent, as such:

void CPTopTweakDlg::OnActivate(UINT nState, CWnd* pWndOther, BOOL
bMinimized)
{
   //CDialog::OnActivate(nState, pWndOther, bMinimized);
}

Evidently nothing was happening in the OnActivate anyway because
everything seems to be fine. Stubbing it out solved the resize issue.

Posting this in case anybody else runs into this stupid problem.
